Specification of Letters Patent.

Application filed September 20, 1920. Serial No. 411,438.

To all whom it may concern:

Be it known that I, dorm B. .OCoNNoR, a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented a certainnew and useful Improvement in Detachable Supports, of which the following is a specification.

My invention relates to racks or hangers, and while they may be used for various purposes, a good illustration is in the case of tool rooms in machine shops where it is necessary to store in an orderly manner, for instant use, milling cutters, drill jigs and other tools and equipment. The object of the invention is to provide a rack in which the pegs or hangers proper are readily adjustable and secure when adjusted. Another object is to construct the device in such manner that the hangers may be adjusted universally-that is, uniform distancesboth horizontally and vertically. Still another ,object is to adapt the idea to sheet metal and to production by the aid of few dies of simple-form.

I accomplish these objects by the construction shown in the accompanying drawings in which Figure 1 is an assembly View in perspective showing two hangers of different desi 11 mounted on the upright.

igures 2, 3 and 4 illustrate the sequence of movements followed in attaching a hanger.

Like numerals denote like parts throughout the difierent views.

According to the design selected to illustrate the principles of the invention; a sheet metal upright 1 is perforated upon given centers, for example, one inch, thus producing horizontal and vertical rows of holes 2. A sheet metal base plate 3 about an inch square, provided either with a peg 4 or check hook 6, has prongs at each corner, two of these prongs 8 extending substantially upward and two others 10, projecting substantially downward. The prongs also extend backward from'the plane of the base plate so as to penetrate the holes in the upright. The parts are so formed and proportioned, and the position and diameter of the holes plate is raised as far as permitted by the up-- per prongs, the lower prongs will clear the bottom of the holes they penetrate, thus ermitting them to be withdrawn, after w ich the upper prongs may be withdrawn and the base plateremoved.

The operation will now be evident: When it is desired to apply a hanger, the upper two prongs are first inserted in an upper pair of holes, as shown in Figure 2. Next, the base plate is swung toward the upright and the lower prongs inserted, as shown in Figure 3. Finally the base plate is lowered until the lower prongs seat on the lower edge of their holes, as shown in Figure 4. The upper prongs are so long that when the lower prongs are thus seated they will extendabove the top of the upper pair of holes, thus holding the hanger in place. It has been found in practice that when the hangers are empty, they may be removed very easily, although they are not readily knocked off by-accidental contact with external objects; but when loaded, especially with such articles as milling cutters or other metallic and relatively heavy things, they are remarkably secure in their position and very seldom come off except by deliberate action of the attendant. Sidewise knocks and those coming from above have no effect whatever to dislodge a hanger, and even those coming from below are not effective except in "unusual cases. Thus the hangers may be readily shifted from one place to another in the upright, are simple to produce, and when positioned are abundantly secure for all ordinary purposes.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

The combination with a sheet metal upright provided with spaced holes, of a substantially rectangular sheet metal base plate having apair of spaced tabs extending from both its upper and lower edges, said tabs being bent to be engageable respectively supporting member extending outwardly through selected holes to detachably interfrom the base plate, said base plate being lock with and support the base plate from disposed in parallelism to the upright when 10 the upright, the upper pair of tabs extendin its supported position. 5 ing backward and upward and the lower In witness whereof, I have hereunto subpair of tabs extending backward and downscribed my name. ward with respect to the base plate, and a JOHN B.
